Auto Watering System

Use the moisture sensor to measure the moisture level of the plants soil on a continuous loop. Then, use the water pump to water the plant when the moisture level is low. Use the LED light to indicate the moisture level of the soil.

Big Idea

Delve into the realm of smart farming and real-time resource management in this lesson. Explore the transformation in agriculture through automated watering systems, vertical farming, and intelligent monitoring.

Understand how farmers are harnessing technology and automation to minimize their environmental footprint while catering to the expanding global population’s food needs.

Take Action!

In the “Take Action” section of this lesson you will take all the knowledge you learned and apply it to creating your own advanced agriculture solution. Creating an auto watering system that consistently monitors soil moisture and only watered when needed!

The goal of this project is to understand how auto watering systems work and how they can support the effects to save water then growing our food.
